绿色粉煤灰商品混凝土耐久性能研究及机理分析

Green fly ash commodity concrete durability research and mechanism analysis

在基于国家现行《普通混凝土配合比设计规程》(JGJ55-2011)6.2.5条中对耐久性有设计要求的混凝土应进行相关耐久性试验验证,本文研究了兰州地区某商品混凝土站的有耐久性设计要求的粉煤灰混凝土的抗渗性、后期强度和抗冻性等一系列耐久性能。以此引起大家对商品混凝土耐久性的关注,深入开展这方面的研究并找到提高商品混凝土耐久性的有效措施。

Based on the current national “normal concrete mix design procedures”（JGJ55-2011） 6.2.5 bar design requirements for durability of concrete durability test should be carried out relevant verification, we study in Lanzhou has a durable commodity concrete station design requirements of fly ash concrete impermeability, late strength and frost resistance and a series of durability.In order to arouse the attention of commodity concrete durability, depth of research in this area and to find ways to improve product durability of concrete and effective measures.
